FAQ

Is it safe to use Yelo?

Yes

There's no personal information or messages being stored server-side. You don't have to provide
any kind of username or
password since authentication is delegated to 3rd party entities like Google or Facebook.

When using public computers don't forget to logout properly (also logout from Facebook or
Google) and it might not be a good idea to
store messages and contacts but for private computers, turning it on is recommended for better
performance.

In what countries does Yelo work?

There isn't a straightforward answer to this question.
Email and Facebook notifications of incoming calls and SMS should work everywhere.
To make calls should also work from almost all countries.
The call forwarding functionality is the tricky part!

For call forwarding to work there are two factors that have to be taken into account.

1. Twilio needs to have numbers available in your countries. Check here2. Operators must provide critical call data for call forwarding to work

This second part is the most tricky. What happens is that Twilio relies on the SIP Diversion Header
and some operators are not compliant and when that happens, we can't provide this functionality.

For our experience, most operators from UK, Romania, Hong-Kong, Latvia, Brazil, Greece, New Zeeland, Ireland, Germany, Bahrain, and France are NOT
compliant and call forwarding won't work.
On the other hand, most operators DO work in countries like US, Canada, Republic of Ireland, Portugal, Spain, Italy, Netherlands, Lithuania, Czech Republic.
On others like Mexico or Australia it depends on the operator.

We are constantly updating this list as we get more feedback from our users.

Is data encrypted?

Yes

All server communication uses SSL encryption from the phone and browser

I have an iPhone, can I use Yelo?

Yes

Actually Yelo Phone works with any phone, even with your landline phone.
Android users can answer Yelo calls and access voicemail via the Android App but any user can do the same via the website.
For iOS (and other non-Android ) users the setup needs to be done manually (see instructions) but most of the functionality in the Android app is available also in the web app. So when call forwarding is enabled you can answer your calls on Yelo via the website.

Do I need to give away my mobile number?

No

You don't need to provide your mobile number to use Yelo but you must do so if you want to
forward your calls to Yelo, use Voicemail, make Yelo 2 Yelo calls or
if you want to make calls with Yelo using your number. For these functionalities you need verify
your number.

Do I need to have an Android phone to forward calls to Yelo?

No

If you want to redirect your calls to Yelo you can use any phone as long as your operator
supports call forwarding (mobile or land line) and you can set it up manually. You can access
your voicemails and receive calls
straight from your browser. For more information you can go to the setup
page

Can I make calls using my mobile number?

Yes

But to be able to make calls using your own number it's required to verify that you actually own
your number.
The verification process needs to be started by the user. Once the user requests to verify the
number the system
will call the number and the user will have to type a code shown on the screen.
If the verification is successful all outgoing calls made by Yelo will use your own number and
whoever the
user calls will know who is calling even though you are calling from a tablet or browser.

We make sure that your number is safe with us and we will not sell any of your private
information or SPAM you with unsolicited messages.

Can I receive calls on my tablet or browser?

Yes

When voicemail is activated and you can't answer a call on your phone Yelo will transfer the
call from your phone to a tablet or browser.
Only then, if the call is not answer it goes to voicemail.
To activate voicemail you need to activate call forwarding but it depends if your operator or if
your mobile subscription plan allows to activate
call forwarding from the phone. To activate call forwarding go to setup page.

Experimental It's also possible to define which call
forwarding
codes to use for activation and deactivation.
By default Yelo uses the code for unconditional call forwarding (**004*) on GSM networks

Why do I always get Connection timeout messages?

Some wifi routers/hubs experience issues with GCM
which is the mechanism used to communicate between the servers and the mobile devices.
If you're using wifi as the source of your connection you might be experiencing this issue. This
is not so common over 3G or mobile connections.

for more infoIf you are experiencing these kind of issues you can always download GCM Wifi
Fix App from Google Play Store

If your device is turn off or offline without internet connection you will also experience this
behavior

Why do I see this on my screen?

For the latest Chrome browsers Twilio
uses WebRTC
as the communications protocol for VoIP calls. This dialog popup up when Chrome requests
permissions to use the microphone as an input source when making calls. For your
convenience we advise you to always allow access to the microphone so that you don't have to do
this every time you make or receive a call.

If your browser does not support WebRTC then it's very likely that Twilio
will use the flash plugin for VOIP calls and
this is how it looks like
It's required to setup the flash permissions in order to make calls so you should allow the
microphone access.
If you choose to remember the settings you will never have to do it again.

I forgot my phone before installing the application can I still use Yelo?

I'm afraid that in this scenario there's not much it can be done. There's no way to run any
application on Android after installation
without the user interaction. If there's someone one that can install and run the application
for you, then you can still use the application

Why do I get incoming calls and voicemails from +266696687, +7378742833, +8656696 or
+266696687?

This usually happens when operators do not provide caller id information when forwarding a call
to a number. When this happens
operators usually provide these numbers that mean:

How much does it cost to send SMS?

SMS are sent through your device so it's just like if you are sending an SMS yourself meaning
that SMS costs will
depend on your current plan.

Sometimes I can't disconnect a call, what can I do?

This is something that we know it happens but seems to be related with the browser.
Please restarting the browser and try again.

What is the difference between Host mode and Client mode?

On Android devices you can run the application is different modes, Host and Client.

Host mode should be used on your smartphone. If you use Yelo on two different Android
smartphones with different
numbers you should run in Host mode on both devices.

Client Mode is supposed to be used on devices that are not your primary device. So you
can run Yelo in
client mode on an Android tablet or another smartphone. Imagine this scenario where you've setup
your primary
device in Host mode. If you lost your phone or ran out of battery you can login on your tablet
or on the
smartphone of a friend and still receive your calls on this device. Same thing happens if you
login on a
browser which runs by definition in Client Mode.
